How to remove the white lines on the sides of Tkinter?

Question

enter image description here

As you can see in the screenshot, my program has white lines on the left and top, how can I remove them? I would like them not to be there at all.

import ctypes as ct
from tkinter import *
def dark_title_bar(window):
    window.update()
    DWMWA_USE_IMMERSIVE_DARK_MODE = 20
    set_window_attribute = ct.windll.dwmapi.DwmSetWindowAttribute
    get_parent = ct.windll.user32.GetParent
    hwnd = get_parent(window.winfo_id())
    rendering_policy = DWMWA_USE_IMMERSIVE_DARK_MODE
    value = 2
    value = ct.c_int(value)
    set_window_attribute(hwnd, rendering_policy, ct.byref(value), ct.sizeof(value))

win = Tk()

background_menu = PhotoImage(file="background-menu.png")
canvas_authorization = Canvas(win, width=1280, height=720)
canvas_authorization.grid()
canvas_authorization.create_image(640, 360, image=background_menu)
dark_title_bar(win)
win.geometry("1280x720")

win.geometry(str(win.winfo_width()+1) + "x" + str(win.winfo_height()+1))
#Returns to original size
win.geometry(str(win.winfo_width()-1) + "x" + str(win.winfo_height()-1))

win.geometry("1280x720")

win.mainloop()
